'CARBURETER SPECIFICATION forming part of Letters Patent No. 669,309,dated March 5, 1901.

Application filed October 15, 1900. Serial No. 33,139. (No model.)

To all whom t may concern:

Beit known that we,OscARADELBERT LANE and HUDSON ALBERT DAVENPORT,citizens of the United States, residing at Adrian, in the county ofLenawee and State of Michigan, have invented certain new and usefulImprovements in Gas-Generators, of which the following is aspecification, reference being had therein to the accompanying drawings.

The invention has reference to a gas-generating apparatus particularlydesigned for making gas from hydrocarbon oils; and the essential objectofthe invention is to produce a gas-generator of this type that will besimple in construction, permitting it to be manufactured at slight cost,and compact in formation, whereby it will occupy a minimum amount ofspace and will be capable of being readily transported.

I/Vith this object in View the invention consists in the novelconstruction of the gas-generator and in the peculiar arrangement andcombination of its various parts, as will be more fully hereinafterdescribed, and shown in the drawings, in which- Figure lis a verticalcentral section through the generator; and Fig. 2 is a cross-sectiontaken on line a: Fig. l.

In construction the generator comprises, essentially, a vaporizer,(designated by the reference-letter A,) a mixer B for mixing the vaporwith the air to produce combustible gas, a valvecontrolled connectionbetween the mixer and the vaporizer, and means for conveying the gasfrom the mixer to the point of consumption.

The mechanism comprising the vaporizer consists of an inlet or supplypipe C, through which gasolene or other duid to be used in generatingthe gas passes to the apparatus -from a suitable source of supply.

D represents a filter-pipe, of a-ny preferred construction,communicatingwith the supplypipe and forming a continuation of the same, and E is aretort or generator proper mounted upon the upper end of the lterpipe,asshown. The retort is preferably in the form of a hollow disk providedwith inlet and outlet ports ot b, diametrically arranged, and a port cat one side thereof. Beneath the retort and arranged upon thefilter-pipe for vertical adjustment is the-burner F, having an opening dat one side thereof and provided at its lower end with a tubular bearinge, adapted to be sleeved over the filter-pipe. A set-screw f within thebearing secures the burner on its support at the required distance fromand beneath the retort.

The burner comprises in its construction a metallic casing preferablycylindrical in configuration, open at. its top, as at q, and havingarranged Within an annular foraminous diaphragm G, which divides theinterior of the casing into a mixing-chamber H and a combustion-chamberI, as plainly shown in Fig. l.

J designates a pipe leading from the porto in the retort down to theopening d in the burner, and K is a nozzle upon the pipe directed towardthe ope ning last referred to and controlled by a needle-valve L.

M is a shield or deiiector-plate swiveled upon a stud 'L' upon thenozzle K, and O is a drip-cup secured to the stud referred to andarranged immediately beneath the nozzle and shield.

Above the retort E and fixed Within the opening b is a Valve-casing P,provided with a needle-valve Q, controlling the escape of the vaporthrough the valve-passage j into the pipe K. The valve-casing referredto is provided with a tubular extension R, with which the pipe K hasathreaded engagement, and in the extension is formed one or moreair-inlet ports S, as shown. vThese ports are controlled by a Valve T inthe form of a sleeve U upon the extension of the valve-casing, thesleeve having corresponding apertures formed therein adapted to registerwith or to close the apertures in the tubular extension R, as may bedesired. The tubular extension of the valve-casing P constitutes theinclosing wall of the mixer B, and the mixing of the vapor with the airis controlled by the valve T referred to through the agency of asuitable handle V.

The reference-letter W designates a condenser mounted upon the pipe Kimmediately above the mixer B, the pipe K extending Within thecondenser, as shown, to a point in proximity to the condenser-top.

The letter X designates a tubular extension upon the upper part of theVcondenser, in which is arranged the pipe Y, leading from the condenserto the point of consumption.

Z is a flaring hood depending from the pipe Y Within the condenser andextending partly over the pipe K.

The condensation is conveyed from thc condenser by means of a pipe e',which communicates with the lower portion of the condenser, as shown. f

In operation the gasolene is conveyed to the retort through the supplyand filter pipes, and the needle-valve L is opened to admit a smallquantity of the gasolene to the drip-cup O, the gasolene being conveyedto the cup by means of the shield M. The valve referred to is thenclosed, and the gasolene Within the cup is ignited to furnish theinitial heat to the generator. The shield M is then turned out of thepath of the nozzle K, and the valve is opened to allow the jet to enterthe opening CZ in the mixing-chamber H. The mixed air and vapor passesfrom the mixing-charnber referred to through the foraminous partitioninto the combustion-charnber, where it is ignited and burns beneath theretort. This will generate vapor within the retort, which by means ofthe valve Q is allowed to pass into the mixer B, where it is mixed withair entering through the apertures S and passes onward through the pipesK and Y to the point of consumption. The condensation passes down fromthe pipe Y to the Haring hood Z, drops from off the edge of the hoodinto the interior of the condenser, and is conveyed away from the latterby means of the overflow-pipes Z.

From the description of the gas-generator it will be readily seen thatthe ports are so arranged relative to each other that a compactapparatus is formed, and the construction of the apparatus is such thatthe parts may be readily separated from each other to permit of theirbeing packed in a small space for transportation or storage; also, thatby the use of the peculiar form of retort that we employ the vapor maybe quickly generated and the adjustment of the burner to or away fromthe retort can be effected in a ready and effective manner to producethe desired results. It will also be obvious from'the construction ofthe mechanism that, if desired, the generator-burner may be permitted toburn constantly, which dispenses with the necessity of Vstarting theapparatus each time the gas is to be used; also, that the means weemploy for regulating the admission of the air With'the vapor may beused for the purpose of preventing the gas in the pipes from returninginto the room where the apparatus is located when the discharge of thegas is shut oft' at the point of consumption.

What we claim as our invention isl. In a gas-generator, a Vaporizercomprising a retort a burner in operative relation to the retortconsisting of a casing having inlet and outlet openings formed thereinand a foraminous partition intermediate the openings dividing theinterior of the casing into a mixing-chamber into which the inlet-opening leads and a combustion-chamber, means for supplying a fluid to theretort, a nozzle directed toward the inlet-opening in the burner, and avalve-controlled pipe connection between the nozzle and the retort.

2. In a gas-generator, a Vaporizer comprising a retort, a burnertherefor consisting of a cylindrical easing having an inlet-openingformed in its cylindrical wall, and having one end arranged adjacent tothe retort and provided with an opening therein, and an annularforaminous partition Within the casing intermediate the openings anddividing the interior of the casing into a mixing-chamberand anopen-ended combustion-chamber, means for supplying a iluid to theretort, a nozzle directed toward the inlet-opening in the burner, anda'valve-controlled pipe connection between the nozzle and the retort.

In testimony'T whereof we affix our signatures in presence of twowitnesses.
